China nears completion of original 26 units of Three Gorges

China is nearing completion of the last of 26 original turbines planned for 22,400-MW Three Gorges Dam, the world’s biggest hydropower project.

The official Xinhua news agency quoted plant manager Ma Zhenbo September 8, saying the installation will be completed by November, when the final 700-MW turbine will begin full operation, a year ahead of schedule.

The plan for Three Gorges, which has a budget of more than US$20 billion, originally called for 26 generators, 14 on the left bank of the Yangtze river and 12 on the right for a total of 18,200 MW. The turbine now being fitted is the last of those.

The project has since been expanded further, with another six turbines being added by 2012 for a total of 22,400 MW. (HNN 3/5/08)

Seven units of 6,300-MW Longtan to operate this year

Xinhua also reported seven units of the 6,300-MW Longtan hydroelectric project are to be operating by the end of the year on the Hongshui River in China’s Guangxi Zhuang Autonomous Region.

The first three turbine-generators of Longtan, China’s third largest hydro project, began commercial operation in December 2007. (HNN 12/31/07) Construction of the plant started in 2001; all nine units are to be operating by the end of 2009.

China Datang invested 30 billion renminbi (US$4.38 billion) to build the 216.5-meter-tall dam, a ship lock, and an underground powerhouse. Construction began in 2001 and is to be completed at the end of 2009.

Voith Siemens Hydro Shanghai delivered the first of seven 715-MW Francis turbine runners to the project in 2006. Its consortium partner, Dongfang Electrical Machinery Co. of China, is manufacturing the balance of equipment.
